CN2290843Y - Hand swing-weight balance - Google Patents

Abstract

The utility model discloses a hand swing-weight balance. The front side of an annular casing is provided with a pointer reading disc, a swing-weight mechanism and a point mechanism are arranged between T-type supports in the casing, the swing-weight mechanism is provided with two swing rods which are symmetrically arranged, and two sector teeth which synchronously swing with the swing rods drive a pointer gear. The utility model is characterized in compact structure, high measuring precision, little man-made sabotage and convenient carrying and workpieces are fully sealed in a cortical shell. In addition, the utility model is conveniently used by flowing venders.

Description

Portable pendulum thallium scale

The utility model is a kind of measuring apparatus of weight, is the substitute products of Hand-held lever scale.

Existing Hand-held lever scale adopts lever principle, is easy on the structure fake.The weighing process is done trick easily, can change the weight of scale thallium, and calibration is the point-like mark.Do not have the direct-reading numeral, reading error is big, may occur misreading.Existing tortoise shape scale, the fish tail scale must carry inconvenience to cheap-Jack fixedly using on the case.And more advanced electronic scales, price is more expensive, and it is former to need external electricity, also is not easy to cheap-Jack and uses.

The purpose of this utility model is to provide a kind of reading directly perceived, structure sealing, the portable accurately pendulum thallium of the precision that is difficult for playing tricks scale.

The utility model adopts lever and eccentric wheel to be combined in and moves and stop at the equilibrium position operating principle on the same fulcrum.Under generating gear drove partially, pointer stopped at scale relevant position, sense data.

Below with reference to embodiment description of drawings ins and outs.

Fig. 1 is the utility model outside drawing;

Fig. 2 removes cut-away view behind the shell for Fig. 1;

Fig. 3 is Fig. 2 side view;

Fig. 4 is pendulum thallium mechanism outside drawing;

Fig. 5 is Fig. 4 side view;

Fig. 6 is the point gear outside drawing;

Fig. 7 is the range multiplier front view;

Fig. 8 is the another kind of structural drawing of range multiplier.

The utility model has by two T type framves 15 and is the annular watchcase 7 of carriage, and there is a portable mechanism watchcase upper end, is made up of anti-friction ring 6 and handheld ring 5.The annular outer cover front is a total indicator reading dish 14, and pendulum thallium mechanism and point gear are housed between two carriages in the watchcase.Fig. 4 sees in pendulum thallium mechanism, it is made up of the fork that two symmetries are assemblied in the same rotating shaft, the fork upper end is an eccentric wheel 4, the lower end is a thallium 1, the centre is a V shape pole 16, eccentric wheel 4 far-end outers respectively have a steel band 3, two steel band lower ends to be connected in the rocking arm far point of range multiplier 11 through leader tape fork 2, and range multiplier rocking arm near point is connected with the load hook 18 of scale; Point gear has two sectors, it is swung synchronously with the V shape pole of pendulum thallium mechanism, and one of them sector is outer knuckle-tooth 13, and another sector is an internal-round gear 17, be engaged in a pointer gear 12 between two sectors jointly, pointer 8 rotates synchronously with pointer gear 12.

In same point two forks are arranged among Fig. 2, arrange respective angles under steel band P P effect, to institute weighing position, the range multiplier design can be according to the different choice rocking arm swivel arm ratio of range through the sector push pointer, Fig. 7, Fig. 8 are the range multiplier of two kinds of different arm of force ratios, and 9 is pointer shaft among Fig. 2.

The utility model is easy to carry, and reading is more directly perceived, and all parts all are enclosed in the betal can, and are not quick detachable, and its ratio of precision of artificial destruction is difficulty, compact conformation, and long service life adopts the low-friction coefficient bearing, can guarantee its weighing sensitivity.
